Man the manhua is going completely out-of-whack with the novel now, this fight never happened there, the 7 guardians didn't have such a big role and were a lot more hostile except for sea-horse doulou.
@Ptakers He's gonna buff the Clear Sky Hammer once he buffs the Blue Silver Grass Emperor all the way, the plan is to fill the Clear Sky Hammer with Black Spirit Rings (and above) only, sure he could do that now, but if he does it as a Dou Luo it would be easier, essentially, he's gonna cheat.
